About me
Hello! I am a Ph.D. candidate in Computer Science at Georgetown University located in Washington, DC. I am working with Prof. Lisa Singh on Data Science, Social Media Mining and NLP.
Most of my projects are collaborations with CNN, Washington Post, UMich and MDI on leveraging AI/ML methods for data-centric social concerns such as sentiment analysis, stance detection, force-migration, gun policy, MeToo movement, spam, misinformation and fake news. I spent some time working at 
Twitter and 
Google.
